Abstract

The invention discloses a vehicle three-dimensional model deformation method and device and electronic equipment, and relates to the technical field of image processing. According to the specific implementation scheme, adjusting a source three-dimensional model of a vehicle, so that a three-dimensional bounding box of the source three-dimensional model is aligned with a three-dimensional bounding box of a target model; obtaining a three-dimensional structure of the adjusted source three-dimensional model; according to the target model, performing local deformation on the three-dimensional structure to obtain a transposed matrix; and according to the transpose matrix, moving the adjusted three-dimensional points on the surface of the source three-dimensional model to obtain a deformed three-dimensional model. Since the source three-dimensional model of the vehicle is deformed according to the target model, manual participation is not needed in the process of obtaining the deformed three-dimensional model, and the model deformation efficiency is improved.

Description

technical field [0001] The present application relates to image processing technology in the field of computer technology, in particular to a vehicle three-dimensional model deformation method, device and electronic equipment. Background technique [0002] Automatic deformation of 3D vehicle models is a necessary way to construct dense mapping relationships between vehicle models, and an important step in constructing vehicle deformation templates. It has important uses in the fields of geometric model analysis, 3D automatic modeling, and 3D model simulation. [0003] At present, the methods for realizing the automatic deformation of the 3D vehicle model include: manually moving the 3D vertices and triangle patches to realize deformation from one model to another; or, using a deep neural network to generate a variety of 3D models, but training Neural networks still require a large amount of manually labeled data. [0004] In the deformation method of the above-mentioned thr...
